Analysis of Multi-Storey Building Considering Wind Effects
Keywords:wind forces, maximum storey displacement, shear wall, shear wall positioning
In this modern era of building construction, the demand for tall structures has been increasing immensely. The horizontal land space is almost exhausted in many places. This has forced people to occupy vertical spacing. The increasing demand in the construction of tall buildings has lead to development of new technologies in the field of construction. As the height of the building raises high above the ground, the wind forces become predominant. This results in the abnormal behavior of the structure. For the safety of the structure, a proper analysis and clear understanding of the wind forces are required. The main factor to be considered is the maximum storey displacement. The top storey displacement of the structure is studied for a multistory building. This structure is provided with shear wall at various positions in order to reduce the lateral displacement. A shear wall is provided to counteract the effects of lateral load acting on it. Seismic load and wind load are the two common loads shear wall is designed to carry. A shear wall of 200 mm thickness is provided in this study. Five different shear wall positioning have been provided and the top storey displacement of the structure is studied. The research aims at understanding the behavior of the structure every time the shear wall position is changed. Software analysis of the structure has been carried out with the help of E-Tabs. The detailed analyses have clearly shown that there is a significant change in the maximum storey displacement at the given shear wall positioning. The shear wall positions can be improvised in order to provide better stiffness and moment of resistance to the structure. The values of each and every analysis have been noted and detailed performance of the structure is studied.
